A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Fexofenadine can be taken with or without food, and there are no specific interactions with magnesium hydroxide. However, it’s always important to consult a healthcare provider before combining medications.

Choice B rationale:

While staying hydrated is generally good advice, there’s no specific requirement to drink up to one liter of fluid per day while taking fexofenadine.

Choice C rationale:

Fexofenadine should not be taken with fruit juices such as orange juice because they can decrease the absorption of the medication, making it less effective.

Choice D rationale:

Fexofenadine can cause side effects such as dizziness or drowsiness in some people. Therefore, it’s important to avoid driving or operating heavy machinery until you know how this medication affects you.

Choice A rationale:

Hydrochlorothiazide is a diuretic medication and does not interfere with the absorption of tetracycline.

Choice B rationale:

Antacids can interfere with the absorption of tetracycline, reducing its effectiveness. Therefore, they should be taken 3 hours before or after taking tetracycline.

Choice C rationale:

Lovastatin is a lipid-lowering medication and does not interfere with the absorption of tetracycline.

Choice D rationale:

Acetaminophen is an analgesic and does not interfere with the absorption of tetracycline.
